<p>The container (1) has a circular base element (3) with a convex shape in view from exterior, where the container is made of metallic material such as aluminum and steel. The element is deformed from the convex shape to a concave shape in view from exterior, by application of pressure on its external surface, for ensuring the push toward the exterior of a conditioned foodstuff (2), where the push releases the passage for air around the foodstuff for supporting the demolding of the foodstuff.</p> |
